Description

Composite electrode and massage device

Technical Field

The utility model relates to the technical field of massage, in particular to a composite electrode and massage equipment.

Background

The flexible electrode has good conductivity and flexibility, is commonly used for electric pulse massagers (such as waist massagers and neck massagers), but has surface resistance generally larger than 100 omega, and the massage strength is general, and the resistance is gradually increased along with the increase of the use times, so that the massage strength of the massagers is reduced. Reducing the resistance by adding conductive fillers to the flexible electrode is one of the ways to improve the above problems. However, this method may significantly increase the cost, and may reduce the flexibility of the film, exacerbating the problem of shedding of the conductive filler. On the other hand, the electrodes of the massage instrument have a certain area, and the difference of the resistance of the areas on the electrodes, which are different from the distances of the contact points, is large, so that the massage force of the electrodes is uneven.

In summary, the existing electrodes of massage devices still need to be improved.
